NEVER MIND: Was: Crash dump of RHEL5, what does "SHARED" memory represent in kmem -i output?

[James Washer <washer@xxxxxxxx>]

From the source I find

 /*

* Get shared pages from dump_mem_map(). Note that this is done

* differently than the kernel -- it just tallies the non-reserved

* pages that have a count of greater than 1.

*/

In the data below, what memory usage is reported as SHARED? Does this imply SysV shared memory, or pages shared between processes, or something else all together?
